I was on Ambien for about 4-5 nights a week for about 2 months and about a week ago I decided I didn't need it anymore. I get the common withdrawal side effect of not being able to sleep as well without it (I only get a few hours a night) but that isn't what is bothering me. I've been having these terribly realistic nightmares, almost like its a lucid nightmare. All these nightmares are like horror movies. It is the most terrible thing I have experienced as far as nightmares and I'm wondering if this is a normal side effect of withdrawal? I see people complaining of having nightmares while ON ambien, but its just the opposite for me.
